Heat oven to 375°F. Separate dough into 5 biscuits; place on ungreased cookie sheet. Brush tops with egg white. Sprinkle with caraway seed. Bake at 375°F. for 11 to 13 minutes or until golden brown.
Meanwhile, in small bowl, combine coleslaw blend and salad dressing; mix well.
Remove biscuits from oven. Split warm biscuits; place bottom halves on same cookie sheet. Set top halves aside. Top each bottom half with coleslaw mixture, beef and cheese.
Return to oven; bake an additional 3 to 5 minutes or until cheese is melted and sandwiches are hot. Cover with top halves of biscuits.
